HEATING AND VENTILATING SYSTEM.

$PECIFICATION forming part of Letters Patent No. 346,623. dated August3, 1886. Application filed December 12. 1885. Serial No. 185,540. (Nomodel.)

To all whmn it may concern.-

Be it known that I, Hermon O. STROUT, a citizen of the United States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented certain new and useful Improvements in Heating and VentilatingSystems, of which the following is a specification, reference being badtherein to the accompanying drawings.

My invention relates to a system of heating and ventilating buildings;and it consists in the arrangement in a building of suitable heating andventilating means, which will be more fully hereinafter described, anddefinitely pointed out in the claims.

One object of my invention is to equalize by suitable means thetemperature of buildings uniformly throughout and avoid direct drafts,or an unequal distribution of hot air, by means which are simple inconstruction, easily operated, and controlled.

A further object of my invention is to cause an equal circulation of hotair through the apartments of buildings,,so that both the upperand-lower portions of said apartments shall be of the same temperature,being regulated by a continuous intermingling and commingling of coldand heated air, which enters rooms and escapes therefrom throughregisters situated-in different parts of the apartments.

A still further object of my invention is to so arrange the ventilatingmeans that cold air has ingress from the top of the building, and iscarried down close to the flooring of the uppermost hallway by asuitable duct, and thence circulate down through the remaining hallways,and eventually enter a duct leading to a furnace.

I attain these objects by the construction illustrated in theaccompanying drawings, wherein like letters of reference indicatesimilar parts in the several views, and in which- Figure 1 is alongitudinal vertical section of a building with my improved heating andventilating devices applied thereto. Fig. 2 is a transverse verticalsection on the line m m of Fig. 1.

Aindicates a building, which, as illustrated, has hallways B B andapartments B B. These apartments have suitable heating-registers, b 1),arranged in their uppermost parts, and coldair registers b b in theirlowermost parts.

These registers 12 and b are arranged in different portions of the room,one above the other, and connect with the hallways B B.

On the ground-flooqas illustrated in the drawings, a suitable furnace,G, is situated, which is surrounded by a heating-jacket, O. This jacket0 has a conical top, a, which, by means of a short pipe, 0', passesthrough the flooring above it into the lower hallway, B. The jacket 0 isopen at its lowermost part, and has a cold-air duct or ducts, O", whichalso run up to and through the flooring of the lower hallway, B. Theshort pipe 0' of the jacket 0 and the cold-air duct 0 are each providedat their upper ends with suitable registers, c and c Atthe rear of thebuilding and extending downward through the roof are two ducts, I) andE. The duct D extends downward to and through the uppermost ceiling inthe upper hallway, B, and has a register, d, in the lower end thereof.The duct E passes downward within a short distance of the flooring ofthe uppermost hallway, B, and has a register, 0, situated in its lowerend. The duet D is an egress-passage for the surplus heat, and extendssomewhat above the level of the duct E on the outside of the building,the said duct E being an ingress-passage for cold air.

This construction having been fully carried out, the operation of myimproved heating and ventilating system will be as follows: The firehaving been previously started in the furnace O, the registers a and care opened and the heat admitted into the lower hallway, B. By awell-known law of physics it then ascends to the highest point oruppermost hallway by means of the staircase-openings. The heat continuesto ascend, passing in through the upper registers, 12, of the upperapartments, and forcing the cold air out through the lower registers,72, into the hallways. The heated current continues to circulate throughthe upper apartments, and gradually forcing the cold air down from floorto floor until the first floor is reached, and the same process ofcirculation goes on until the heat of the entire building has becomeequalized. The cold air that has been been forced downward by the heatedcurrent gradually flows out into and along the hallways until it reachesthe first floor and enters the duct 0 and is conducted to the furnace O,and again directed into the hallways in a heated state. When the heathas become equalized and has all passed through the furnace 0 once, theoxygen will 5 havebeen more or less destroyed, and to ventilate andameliorate the building the register 6 in the cold-air duct E is opened,a quantity of cold air supplied to, the building, which againlfurnishesa renewed supply of, oxygen. WVhen the heat becomes too excessive, theregister d'in the escape-duct D is opened and allowed to remain openuntil thereis an equalization of both heat and oxygen. If it is desiredto heat only a portion of the building, the registers are closed, whennecessary. By this continuous circulation through the apartments auniform temperature is established and retained in all of theapartments, rendering the lower portions of the rooms or hallways ofequal temperature with the upper portions thereof. The building is notonly heated in an ameliorated manner, but is at the same time suppliedwith oxygen by the admission of cold air through the duct E, sonecessary to respiration, and, consequently, health. This system ofheating and ventilating can be applied to buildings which are withouthallways, the heat circulating in the same manner from apartment toapartment; or if used to heat churches or large single rooms the samemode of construction and operationlwould be employed. It is alsoevidentthat any form of furnace or stove can be used.

It is obvious that many minor details of construction could be made andsubstituted for those shown and described without in the least departingfrom the nature and principle of my invention.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. In a heating and ventilating system, the combination, with a buildinghaving a series of communicating rooms, of aheater provided withcirculating-pipes located below and connecting with one of said rooms,and suitable egress and ingress ventilators situated in the uppermostpart of the building and communicating with one of the rooms most remotefrom the heater, substantially as described.

2. In a heating and ventilating system for buildings, the combination ofa building having a series of communicating rooms, of a jacketedfurnace, a cold-air duct connected to the lower part of the jacket, theupper portions of thejacket and cold-air duct being supplied withregisters passing through the flooring above, an egress-duct for theescape-of hot air and an ingress-duct for entrance of cold air, situatedin the rear uppermost portion of the building, and upper and lowerregisters in the apartments, whereby the heated air is allowed to ascendinto the uppermost portion of the building and circulate downward,forcing the cold air into contact with the furnace, ameliorating thetemperature by the admission of cold air, substantiallyas described. 1

3. In a heating and ventilating system for buildings, the combination ofa building having a series of communicating rooms, of a heating-furnace,a jacket surrounding the same having a short pipe in the top passingthrough the floor above the furnace, a coldair duct connected to thelowermost part of the jacket and extending up through the floor above,suitable registers in the said jacket and air-duct, suitable ventilatorsfor the egress of hot air and ingress of cold air situated in theuppermost part of the building, and upper and lower registers in theapartments, substantially as described, and for the purposes specified.

4. In a heating and ventilating system for buildings, the combination ofa building having one or more rooms, of a heating-furnace surrounded bya jacket and connected with the floor above, a cold-air duct connectedto the lower part of the jacket and extending up through the floorabove, cold and heat ventilating ducts in the upper portion of thebuilding, and suitable means, as shown and described, for controllingand regulating the temperature, substantially as described.

5. In a heating and ventilating system, the combination of a buildinghaving one or more apartments, of a hcating-fui'nace, (l, a jacket, 0',

surrounding the same and connecting with and passing through the floorabove, a cold-air duct, 0, connected with the floor above and the lowerportion of the jacket 0, ventilatingduets D and E, situated in the upperportion of the building, upper and lower registers, b and I), in theapartments, and means, as shown and described, for controlling andequalizing the temperature, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
